Are there any best practices for handling domain resolution in PHP?

When handling domain resolution in PHP, it is best practice to use the gethostbyname() function to resolve a domain name to an IP address. This function ensures that the domain is resolved correctly and efficiently. 

$domain = "example.com";
$ip_address = gethostbyname($domain);

echo "The IP address of $domain is: $ip_address";
